What is the most significant impact of the green revolution?
Achievements of the Green Revolution In Asia, where the impact of the green revolution was greatest, almost 90 percent of wheat fields were planted with modern varieties and plantings of high-yielding rice had increased from 12 to 67 percent.
Where did the Green Revolution have the least impact?
Which regions were least impacted by the Green Revolution? Sub-Saharan Africa and U.S. Which factor explains an economic limitation to the success of the Green Revolution? Many farmers in the developing world cannot afford the expensive inputs such as machinery, seeds, and fertilizer.
What are the main effects of green revolution on Environment explain?
Green revolution was highly successful as agricultural production of most of countries increased. But Green revolution has some adverse impact on environment in forms of deforestation, land degradation, loss of biodiversity, increase in greenhouse gas emissions etc.
What is Green Revolution when and why it was implemented?
The introduction of High Yielding Varieties (HYV) of seeds and the increased use of fertilizers, pesticides and irrigation facilities arc known collectively as the Green Revolution, which resulted in the increase in crop yield needed to make India self-sufficient in food grain.
What is Green Revolution Why was implemented and how did it benefit the farmers?
The spread of green revolution technology enabled India to achieve self-sufficiency in food grains. It helped in improving the living standard of farmers. Also, it helped in creating marketable surplus of food grains, especially wheat and rice.
How did Green Revolution benefit the farmers?

The Green Revolution has increased the productivity of farms immensely. A century ago, a single farmer produced enough food for 2.5 people, but now a farmer can feed more than 130 people. The Green Revolution is credited for feeding 1 billion people that would not otherwise have been able to live.
How did the Green Revolution lead to an increase in food in the developing world?
The Green Revolution (a term used for rapid increases in wheat and rice yields in developing countries brought about by improved varieties combined with the expanded use of fertilizers and other chemical inputs) has had a dramatic impact on incomes and food supplies in many developing countries.
What was one problem Africa faced in attempting to adopt the green revolution?
As a result poor farmers growing staple food crops in Africa could not adopt the new varieties. What was crucial for Africa was to develop crop varieties that could thrive in water-stressed regions without heavy use of fertilizers. . . .
